DECT Wireless Conference System

overview Function and characteristic Technical Parameter

Product Overview:
The Digital Enhanced Cordless Telecommunications (DECT) system is an enhanced digital cordless telephone standard developed by the European Telecommunications Standards Institute. It is an open, evolving digital communication standard mainly used for cordless telephone systems. It can provide high-quality voice and data services for high-density, small-scale communications.
This conference system is developed using the latest DECT technical standards. The microphone uses the DECT standard authentication algorithm (DSAA2) to pair with the host to ensure that the call is an authorized device. DECT communication includes advanced encryption methods that can effectively prevent unauthorized monitoring of calls. The dedicated telecommunications features of DECT devices ensure more stable and clearer call quality.
